The first lightning will first be visible in the Pyrenees, the Basque country and Béarn. “They could occasionally be strong,” explains La Chaîne Météo, which adds that “on Saturday morning, these storms will be present from Landes to Charente. Accumulated rain could already be abundant in this area (20 to 30 mm in 3 hours). » As for the wind, it should be sustained with gusts of up to 80 km/h on the Atlantic coast.
Accumulations of 50 to 80 mm in Gironde and Landes
The whole morning will be rainy in the South-West. The Weather Channel even announces accumulations of 50 to 80 mm in the south of Gironde and in the Landes. We will have to wait until mid-afternoon for the storms to finally move away, towards the East, even if showers could continue here and there. Rivers could then flood.
By the end of the day, temperatures will have dropped by around ten degrees compared to Friday.
The storm surge will develop in Occitania, in the Massif Central, then shift towards the Centre-East and the North-East, becoming more and more violent. Risks of hail and even tornadoes cannot be ruled out, particularly in Lorraine.
